SWITCH
ARCHITECTURE
The switch performs a wire-speed, non-blocking switching fabric.
This allows wire-speed transport of multiple packets at low
latency on all ports simultaneously. The switch also features
full-duplex capability on all ports, which effectively doubles the
bandwidth of each connection.
This switch uses store-and-forward technology to ensure
maximum data integrity. With this technology, the entire packet
must be received into a buffer and checked for validity before
being forwarded. This prevents errors from being propagated
throughout the network.
NETWORK
MANAGEMENT
OPTIONS
The switch can also be managed over the network with a web
browser or Telnet application. The switch includes a built-in
network management agent that allows it to be managed
in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It
also has an RS-232 console port connector on the front panel for
out-of-band management. A PC may be connected to this port
for configuration and monitoring out-of-band via a null-modem
serial cable. (See Appendix B for wiring options.)
NOTE:For a detailed description of the management features,
refer to the User’s manual.

DESCRIPTION OF
HARDWARE
1000BASE-T
PORTS
The switch contains 24 1000BASE-T RJ-45 ports. All RJ-45 ports
support automatic MDI/MDI-X operation, auto-negotiation and
IEEE 802.3x auto-negotiation of flow control, so the optimum
data rate and transmission can be selected automatically.
SFP
TRANSCEIVER
SLOTS
GS-2328KX supports the Small Form Factor Pluggable (SFP)
transceiver slots are shared with RJ-45 port 21 to 24. In the
default configuration, if an SFP transceiver (purchased
separately) is installed in a slot and has a valid link on the port,
the associated RJ-45 port is disabled.
The following table shows a list of transceiver types which have
been tested with the switch. For an updated list of vendors
supplying these transceivers, contact your local dealer. For
information on the recommended standards for fiber optic
cabling, see “1000 Mbps Gigabit Ethernet Collision Domain” on
page 28.

NETWORK PLANNING
INTRODUCTION
TO SWITCHING A network switch allows simultaneous transmission of multiple
packets, and it can partition a network more efficiently than
bridges or routers. Therefore the switch has been recognized as
one of the most important devices for today’s networking
technology.
When performance bottlenecks are caused by congestion at the
network access point such as file server, the device can be
connected directly to a switched port. And, by using full-duplex
mode, the bandwidth of the dedicated segment can be doubled
to maximize throughput.
When networks are based on repeater (hub) technology, the
distance between end stations is limited by a maximum hop
count. However, a switch can subdividing the network into
smaller and more manageable segments, and linking them to
the larger network than it turns the hop count back to zero and
removes the limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet,
or Gigabit Ethernet network to significantly increase bandwidth
while using conventional cabling and network cards.
APPLICATION
EXAMPLES The GS-2328KX-Port Series Switch implements 24 Gigabit
Ethernet TP ports with auto MDIX and 4 slots for the removable
SFP module (GS-2328KX) which supports comprehensive types
of fiber connection, such as LC and BiDi-LC modules. It is not
only designed to segment your network, but also to provide a
wide range of options in setting up network connections. Some
typical applications are described below.
The switch is suitable for the following applications.
 Remote site application is used in Enterprise or SMB
 Peer-to-peer application is used in two remote offices
 Office network
 High Performance Requirement environment
 Advance Security for network safety application
 Suitable for data/ voice and video conference application

twisted pair (STP) cable with RJ-45 connectors; Category 5
or Category 5e with maximum length of 100 meters is
recommend 100BASE-TX, and Category 5e or 6 with
maximum length of 100 meters is recommend for
1000BASE-T.
◆ Protection from radio frequency interference emissions.
◆ Electrical surge suppression.
◆ Separation of electrical wires and data based network
wiring.
